1 This invention relates to gluing machines for applying glue to paper,cardboard, leather and other flexible or rigid materials employed in themanufacture of paper boxes, luggage, leather goods, games, toys,novelties, display mounts, table pads, desk pads, and numerous otherproducts of flexible or rigid or stiff material. The machines of thisinvention are useful in a vast field of manufacturing purposes wherevera means for readily applying adhesive material to asurface is required.

An object of this invention is to provide an improved table constructionfor gluing -machines 1 Claim. (01. 91- 51) which will permit the gluingof either-thin or thick sheets.

Another objectof this invention is to provid an improved mounting for agluing table which will permit upward swinging of the table to aninoperative position to provide for filling the glue container and whichwill enable the operator to easily and quickly clean the glue roller ordoctor roller, add glue, stir the glue and attend to any operationrequiring quick, easy and ready access to the glue or adhesivecontainer. v out the use of tools or other equipment, the operator mayswing the table unit up and out of the way, in a'manner as hereinafterset forth, the table unit including the feed roll and'top roll, or asthe case may be, the cardboard attachment when the latter is used.

Another object of this invention is to provide an auxiliary table whichis secured to the main table and which will transform the paper sheet orother flexible material gluing machine to a cardboard or other rigid orstiff sheet material gluing machine.

A further object of this invention is to provide an improved feedingmeans for the sheets so that either thin or thick sheets may be passedthrough the machine. I a

A still further object of the invention is to provide an improved rollerassembly which will permit the transformation of the paper sheet orother flexible material gluing machine into a cardboard sheet or otherheavy or rigid or still material gluing machine.

The improvements hereinafter set forth and described provide amachinehaving a combination of functions such as being a machine whichWill-take care of gluing of thin flexible materials York, N. Y., a cor-'as well as heavier and rigid materials up to as much as is"'inthickness without any mechanical changes being required, adjustment forthe different thicknesses being accomplished merely by turning knobs,

With the foregoing objects in view, and others whichmay hereinafter morefully appear, theinvention consists of the novel construction,combination and arrangement of parts, as will be mor specificallydescribed, and illustrated in the accompanying drawings wherein areshown embodiments of the invention, but it is to be understood thatchanges, variations and modifications may be resorted to whichfall'within the scope of the invention, as claimed.

Referring to the drawings the numeral it desigthrough the 'natesgenerally a frame structure having mounted at the upper end thereof aglue receptacle generally designated as l I. The receptacle II includesa bottom wall l2, opposite side walls l3 and M, and opposite end wallsl5 and 6. The receptacle H is openat the top and is adapted to be closedat the top by means of a flat table I1. The table I! issecured to a pairof pivoted side members is which are of like construction. Each sidemember l8 includes an elongated body 19 formed with an ear20 at the rearthereof through which a pivot bolt 2! engages so-that the table I! maybe raised'in order to provide for filling of thereceptacle H. The bodyI9 is provided'with a forwardly extending arm 22 which engages overtheupper side of the table [1. A pair of elongated bars 23, are disposedon -the lower side of the table I! adjacent each longitudinal edge, andare secured to the table IT by fastening members 24. 5

The arm 22, as shown in Figure 1, is upwardly side elevation of theoffset from the lower edge of the body [9, and the bar 23 has the lowerside thereof substantially co-planar with the lower edge 24 of the body[9. The forward end of the table I1 is downwardly bent, as indicated at25, and provides a guide means in addition to a guard for the motorwhich, as will be hereinafter described, is positioned below theprojecting end of the table IT.

The body i9 is formed with a guide slot 25 which is inclined to thevertical, and within which the bearing 2'! for a feed roller 28 isadapted to rotatably engage. A bushing 29 is secured by fasteningmembers36 to the cutout 3l ;formed;in the body is; and a; roller tensioningnutfiz is threaded on a bolt 33 which is connected with the bearing 21.It will be understood that the bearing 21 is spring-pressed topaper-engaging position, and the nut 32, which is threaded-on the bolt33, is adapted to providethe necessary adjusting means for adjustingthebearingfll The feed roller "28 is disposedat the forward end of thetable I7, and is disposed closely adjacent a gluing roller i mounted ona sliaft--35. The shaft 35 is journalled through the sidewalls I3 andi4, and has secured to one end thereof, a gear 36. The gear 36 mesheswith a driving gear .31 of relatively, small. diameter whichis mountedone. shaft 38 carryinga driving pulley p38.

The. pulley 39 has trained thereaboutabelt 40 which is also trainedabout a pulleydl carried by a motor shaft 42, The motor shaft .42 isoperated by. a motor 43 which is securedto a bracket Adextending fromthe front wail l5 of the frame structure.
